Jquery post to Action with Dictionary Parameter

I am feeling dejavu, but I cannot find the answer to this: I have an array of objects that needs to look like this when inspecting a jQ $.post call:

limiter[0].Key
limiter[0].Value

so that it is mapped in the action

public ActionResult SomeAction(Dictionary<Guid, string> dictionary) { }

However, this javasc开发者_运维百科ript:

// Some Guid and Some Value
var param = [ { 'Key' : '00000000-0000-00000-000000', 'Value': 'someValue' } ];

$.post('/SomeController/SomeAction/',
       {
       dictionary: limiter,
       otherPostData: data
       },
       function(data) {
          callback(data);
       }
)

produces this when inspecting it in firebug:

limiter[0][Key] = someKey // Guid Value
limiter[0][Value] = someValue

This is in jq 1.4.2. I seem to remember some flag you need to set to render json a different way in jQ. Does this ring any bells?

Try like this:

var param = {
    '[0].Key': '28fff84a-76ad-4bf6-bc6d-aea4a30869b1', 
    '[0].Value': 'someValue 1',

    '[1].Key': 'd29fdac3-5879-439d-80a8-10fe4bb97b18', 
    '[1].Value': 'someValue 2',

    'otherPostData': 'some other data'
};

$.ajax({
    url: '/Home/SomeAction/',
    type: 'POST',
    data: param,
    success: function (data) {
        alert(data);
    }
});

should map to the following controller action:

public ActionResult SomeAction(Dictionary<Guid, string> dictionary, string otherPostData) 
{ 
    ...
}

var dict = {}
dict["key1"] = 1
dict["key2"] = 2
dict["key3"] = 3

$.ajax({
        type: "POST",
        url: "/File/Import",
        data: dict,
        dataType: "json"
});

public void Import(Dictionary<string, int?> dict)
{
}

just send your obj as dataType: "json"

You can use this flag -

jQuery.ajaxSetting.traditional = true;

To get jQuery to post the data in a different format to the one you are seeing. See this question for further info -

Passing arrays in ajax call using jQuery 1.4

You will see the post param as limiter[0][Key] because jquery serializes the json data before it posts it. This is very well interpreted by the controller action and you get the required input in the action.

You can also use a list of objects and the result will be the same as what you wanted. This is a nice example.
